Major infrastructure changes, part 2.

* Moved helpers, common and triggers dirs into xbps-src, where
  they belong.
* Renamed the templates dir to srcpkgs, it was so redundant before.
* Make it possible to add subpkgs with no restriction in names, for
  example udev now has a subpkgs called "libgudev". Previously
  subpkgs were named "${sourcepkg}-${pkgname}".
* xbps-src: changed to look for template files in current directory.
  That means that most arguments from the targets have been removed.
* xbps-src: added a reinstall target, to remove + install.
* xbps-src: do not overwrite binpkgs by default, skip them.

And more that I forgot because it's a mega-commit that I've been
working for some days already...

+ Glitz is a portable 2D graphics library that uses OpenGL to render hardware
+ accelerated graphics. It supports many of the latest OpenGL features, such as
+ efficient off-screen rendering using pbuffers. Rendering can be carried out by
+ arbitrary OpenGL layers, thanks to glitz's extensible backend system.
+
+ Glitz is designed to match the X Render Extension semantics and provides
+ a general way for accelerating this imaging model. Glitz can be used as
+ a stand-alone layer above OpenGL but is also designed to act as a backend for
+ cairo, providing it with OpenGL accelerated output."
